That equation makes absolutely no sense. You're measuring distance in time squared per distance. Adding a force to a force distance squared per time squared. Taking a logarithm of a dimensional quantity.

E=McÃ‚Â² is the energy an object has in a reference frame where its momentum is 0, it is the minimum possible energy of an object.

F=ma is not valid when just the mass and acceleration are known, mass must also be constant, and velocity <<c. It's also just known as the force not "potential force"

s=ut+(1/2)atÃ‚Â² and vÃ‚Â²=uÃ‚Â²+2as are only valid for constant acceleration and u<<c

Moment of Force = Mass(moment) * acceleration. This is useful if you have one of the stretchy-man kerbal rocket that can't fly strait.

there's a problem with your semi major axis equation, in the apoiler it states:

= Apoapis of orbit (m) - Measured in altitude from surface

= Periapsis of orbit (m) - Measured in altitude from surface

Both should be measured from the center of the body, not from surface. A sphere is the same as a point mass!

Proposal 1/2v^2-GM/r=C

Where:

no thrust is added

r is the distance from the center of the body

You use this to figure out how fast you'll be going at a given point on an escape trajectory (the vis viva equation can actually do this according to wikipedia but I don't know how to calculate the semi major axis of a hyperbola, this is what the nearest physics textbook coughed up)

P.S. I would advise replacing "Measured in:" column with "Dimensions:" column. Units depend on your system, but a length in equation will always be a length, and so on. So that's a useful bit of information
